Chemical structure of Suc-Ala-His-Pro-Phe-pNA

GA23544

Suc-Ala-His-Pro-Phe-pNA

Also known as 4-[[(2S)-1-[[(2S)-3-(1H-imidazol-5-yl)-1-[(2S)-2-[[(2S)-1-(4-nitroanilino)-1-oxo-3-phenylpropan-2-yl]carbamoyl]pyrrolidin-1-yl]-1-oxopropan-2-yl]amino]-1-oxopropan-2-yl]amino]-4-oxobutanoic acid

The rate of isomerization of the histidine-proline bond in the sequence Ala-His-Pro-Phe is influenced by the degree of protonation of the imidazole ring·Suc-AHPF-pNA has also been used as substrate for human mast cell chymase
